I found a dead Great Horned Owl on our property in Lakefield. It had a tag on its leg (#788-30808). I went on-line to https://www.pwrc.usgs.gov/BBL/bblretrv/ and was able to find the following information:
Species: Great Horned Owl
Date banded: 03/16/2009
Banding Location: 5 KM N OF LAKEFIELD, ONTARIO, CANADA
Age: HATCHED IN 2007 OR EARLIER
This means the bird was at least eight years old!
